Description
Technical field
The present invention relates to wireless communication technology field, particularly relate to a kind of concurrent service processing method and device.
Background technology
Along with popularizing of TD intelligent terminal, various colourful application program of mobile phone arises at the historic moment.The client softwares such as QQ wherein, Fetion, microblogging often carry out backstage and automatically run.And these clients are the connection of maintenance and server, have employed heartbeat packet testing mechanism, such as QQ cell-phone customer terminal was every tens seconds or a few minutes meeting is automatic and the webserver carries out the mutual of heartbeat packet, intelligent terminal user is so just caused often to be in the connection of packet data domain business (hereinafter referred to as PS business), if user is when these application programs connect, dial or receive calls, voice and packet data concurrent service will occur.
Voice and packet data concurrent service is the distinct characteristic of 3G, and namely multiple circuit hosting domain business (hereinafter referred to as CS business), PS business occur simultaneously.Voice and packet data concurrent service, while enriching Consumer's Experience, also brings a series of problem.When CS business that the most outstanding is exactly and PS service concurrence, PS business can produce abnormal conditions, takies comparatively multiple resource, thus causes a series of faults such as CS business one-way voice, call drop, causes very bad perception to user.
The all devices producer of current TD-SCDMA network, carries two schemes for voice and packet data concurrent service.A kind of scheme is based upon by voice and packet data concurrent service on R4 carrier wave, and speech business RAB, data service RAB and 3.4K signaling SRB take 4 BRU(and code channel up), descendingly also take 4 BRU; Another kind of scheme is based upon by voice and packet data concurrent service on HSDPA carrier wave, uply takies at least 4 BRU, and the data service RAB in descending voice and packet data concurrent service uses HS-PDSCH, speech business RAB and 3.4K signaling SRB to use two DPCH channels.
Through the assessment to the actual performance of TD-SCDMA network, all there is comparatively serious defect in above two kinds of voice and packet data concurrent service based Carrying Schemes.
The first, voice and packet data concurrent service R4 carriers carry scheme: the TD-SCDMA network of China Mobile is in order to ensure the downloading rate of PS business, R4 number of carriers in a community will be less than HSDPA number of carriers, such as the outdoor macro station of S333, be generally R4 carrier wave be R4 carrier wave with the ratio of HSDPA number of carriers: HSDPA carrier wave=1:2, for indoor Micro-cell, general R4 carrier wave is R4 carrier wave with the ratio of HSDPA number of carriers: HSDPA carrier wave=2:4.By adding up the complaint of existing network, find the network adopting this scheme, in the community that intelligent terminal is relatively concentrated, the complaint of up single-pass remains high.Through on-the-spot test, find that the BRU taken because of each voice and packet data concurrent service user uplink of scheme is for this reason more than the twice of common AMR user, so although this community number of users is also few, but because the user's accounting that there is voice and packet data concurrent service is comparatively large, cause that voice and packet data concurrent service has seriously tied up the physical resource of R4 carrier wave, up code resource utilization is too high.Too high code resource utilization causes again up ISCP and disturbs increase, the up single-pass of final formation even call drop.
The second, voice and packet data concurrent service HSDPA carriers carry scheme: when voice and packet data concurrent service occurs, be carried on HSDPA carrier wave by speech business RAB1 and data service RAB2, RAB1 and signaling SRB is generally mapped in TS6 channel simultaneously, and RAB2 is carried on HS-PDSCH channel: TS3, TS4, TS5.This scheme extensively adopts on the network of the TD-SCDMA of the manufacturers such as middle Xinghe Datang.Carry out the assessment of network quality through the city, Guangdong that the emerging equipment of centering covers, find that the voice and packet data concurrent service call drop that this mechanism causes is comparatively serious.Voice and packet data concurrent service is based upon the reason that HSDPA carrier wave causes cutting off rate high to be had:
1) in voice and packet data concurrent service, data service is carried by HS-PDSCH, data volume is very little, so scheduling times is less, when this user is scheduled once in a while, interval due to HS-SCCH has been greater than the GAP cycle, now HS-SCCH can launch with initial maximum power, causes this user AMR business to be disturbed and call drop by HS-SCCH;
2) during voice and packet data concurrent service, because PS service traffics are very little, so uplink DCH channel needs reduction of speed to arrive comparatively low rate, carry out RB simultaneously and reshuffle, which increase/the risk of dropped calls that goes offline;
3) all TD-SCDMA equipment manufacturers in the industry, during voice and packet data concurrent service, if PS business goes offline, will also discharge the AMR business of normal talking simultaneously, cause the AMR business in voice and packet data concurrent service to be forced release;
4) disturb from neighbor cell co-frequency co-time slot.
As known from the above, all there is the drawback that voice call perception is not good in two kinds of current voice and packet data concurrent service based Carrying Schemes.
